You know it's cold when the news site says the HIGH is going to be 27. And right now it says it's around 10 degrees. then your car won't start because the cold killed the battery so you have get a jump (or if you're like me and have a battery charger but then spend a good hour in said cold weather setting it up) before you can go anywhere. Yeah, that's cold.
At least I'm not having this problem next week, because I would have missed class by now if I were-at least I'm grateful I discovered it this week so it's solved by next week.
